The Australian Bureau of Statistics survey reveals households spend an average of $60 each week on fuel for vehicles, and $39 on gas and electricity for their homes. Households in the Northern Territory face the highest total energy costs of any state or territory, with a weekly bill of $110.
At 20,000 miles per year with a vehicle that gets twenty miles to the gallon you would need 1,000 gallons of gas per year. With gas prices at $2.00 that would cost $2,000 per year. At $4.00 it would cost $4,000 per year. So over the last five years your gasoline bill has increased by $2,000 or $38.46 dollars per week. Better take a few more sack lunches to work. Average consumption depends on your home size and location.
